Psutil correct version dependency

[saaj]

Correct dependency is install_requires=["psutil<2"]. Otherwise pyrasite-gui breaks. It seems psutil version 2 isn't compatible with version 1 around p.cmdline, p.create_time, p.uids, p.gids, etc. With 1.x it's fine.

develop...spaceone:patch-1

Is there any reason why this has not been merged if the patch works?

That's not the only place that get_ has been changed and needs an update. See #26
